This fee, known as a capacity charge, is only incurred when connecting a property to the regional sewer system or increasing your usage. Capacity charges ensure all customers pay their share of the capital costs associated with maintaining, improving, and/or expanding the sewer system due to the increase in flow.
Note: All businesses connecting to the regional system will require a site inspection upon completion of construction. For more information on our annual business survey program, visit our Field Inspections page.
The charge is calculated using three factors: 1) Type of Business 2) Wastewater Flow* (gallons per day) 3) Wastewater Strength* (milligrams per liter)
*For these factors, a standard value is utilized and represents the average historical usage for that business category. If you think your flow and/or strength volumes are less than the standard value, actual volumes may be used instead
A rate formula is then used to convert these factors into your total fee:
Special users are any establishment which cannot be classified in any other category, based on business type, individual flow, and strength characteristics. The capacity charge for special users is ordinarily determined based on actual volumes. See the Capacity Charge Calculation (PDF) for the special user rate formula.
